FRANKLIN 0. WHEELER, OF ST. JOSEPH, MISSOURI, ASSIGNOR OF ONE-HALF TO HENRY CORBETT, OF SAME PLACE.

TROLLEY FOR ELECTRIC STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 433,839, dated August 5, I890. Application filetl April 18, 1890. Serial No. 348,523- (Homo deli) ence being had to the annexed drawings, form-- ing a part thereof, in which- Figure 1 is a side elevation, partly in section, of my improved trolley; and Fig; 2 is a plan view of the same.

'Similar letters of reference indicate corresponding parts in both views.

7 The object of my invention is to provide a trolley for attachment to electric street-cars, in which the jumping of the electric conductor from the trolley will be avoided; also, to fur nish'means for readily reversing the trolley when it is desired to run the car in the opposite direction.

The invention will be first described, and then specifically pointed out in the claims.

The car A, which is of the usual construction, is provided with an electric motor, (not shown,) which is grounded through the trackrails. At the top of the car is arranged a stationary'platform B, to the center of which is pivoted the revoluble platform 0, which turns upon the pivotal bolt a, and is prevented from contact with the platform B by a large washer b. To the standards 0, attached to one end of the platform 0, is pivoted a frame D, formed of side pieces (I, the crosspiece 6, and the cross-bar f. The said frame is movable upon the bolt passing through apertures in the frame and in the standards 0. In the free ends of the side pieces d is journaled a metallic roller E, having at its ends flanges h for guiding the conductor, in contactwith which the roller turns.

In standards 1' is journaled a rock-shaft j, to the ends of which are attached levers k, which extend above the rock-shaft. The free extremities of the arms k are provided with slotted T-shaped ends for receiving adjustable studs Z, which project through slots min the side pieces (Z. To the center of the rockshaft j is attached an arm n, which projects downwardly and is attached to one end of the spring o,'the opposite end .being received on a hook 19, attached to the movable platform 0. In the platform 0, near the end below the free end of the frame D, is placed a tube (1, in which is inserted a bolt 7", provided at its upper end with an eye 3. 5 5

In the stationary platform 13 is formed a socket t for receiving the lower end of the bolt 1". To the same end of the platform 0, near the-bolt r, is attached a standard u, having an eye 1; at its upper end. A spiral spring to, surrounding the standard u, is attached to the bolt 7 and tends to force the said bolt downward. To the cross-bar f of the frame D is attached a cord F, which extends downwardly through the eye 5 of the bolt r, thence upwardly through the eye 1) of the standard u, and thence downwardly within easy reach of the car-driver. The roller E rolls in contact with the overhead electrical conductor G. Ar

its socket t in the platform 13, at the same time drawing down the frame D and breaking contact between the roller E and the conductor G. The platform 0 will then be turned by means of the cord F through a half-revolution, when the roller E will again be brought under the conductor G. In slacking the cord F the spring 0, acting through the mechanism already described, raises the frame D, bringing the roller E again into contact with ":the conductor G, at the same time releasing ithe bolt 0", allowing it to slip into the socketit at the opposite end of the platform B, when the trolley is in condition to run in the opposite direction. f

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In an electric railway, the combination, with the pivoted inclined spring-supported arm having a trolley at its upper end, of a rock-shaft under said arm, providedwith an I upwardly-inclined arm engaging said trolley- I00 arm, and means for operating the rock-shaft, substantially as set forth.

2. In an electric railway, the combination, with a stationary platform having bolt-sockets t t at opposite sides of its center, of a horizontally-turning platform pivoted centrally between said sockets and provided with a vertically-movable bolt adapted to enter. either socket, a trolley-carrying arm, a standard adjacent to the said bolt, and a flexible strand.

provided with the platform B, of the revoluble platform 0, provided with the standards 0 i, the frame D, pivoted in the standards 0, the elongated roller E, journaled in the frame D, the rock-shaftj, the arms 70 42, attached to the said rock-shaft, the spring, 0, the cord F, the bolt 1', and the standard a, substantially as specified.

4. In a trolley for electric cars, the combination of the frame D, formed of slotted side pieces (1, the rook-shaftj, the arms it, having slotted ends, the adjustable studs Z, the arm n, and the spring 0, substantially as specified.
